Rolf Prima Ares4 Disc Wheelset
Details
Shockingly light. Blindingly fast.
The Ares4 does it all. With its 42mm Delta rim profile and paired-spoke technology, it perfectly balances aerodynamics with light-weight. You’ll float up long climbs, save watts on windy flats, master technical descents with confidence, and end the day with a smile.
The rim profile features a 19.5mm internal width and tubeless-ready technology for improved ride quality and compatibility with a range of tire widths. The Ares4 wheels feature our US-made hubs with Enduro bearings, titanium freehub body, and T2 high engagement for instant accelerations and long life — no matter how hard you hammer. Or, pull out the stops with a ceramic Enduro Zero bearing upgrade for even more speed and longevity.
All Rolf Prima orders are built by hand in Eugene, Oregon.
Going tubeless allows you to run lower tire pressures without the added weight of a tube. Lower tire pressure has many benefits, including greater traction, lower rolling resistance over rough surfaces, and decreased risk of a puncture-related flat.
Tubeless-ready rims and tires are parts of a complete system that eliminate the need for tubes by creating an airtight chamber between the rim and tire. Liquid sealant is added to the chamber to fill small punctures and maintain air pressure while you ride.
UST (Universal Standard for Tubeless) is a specific type of tubeless system that dictates the shape of the rim and tire beads. UST rims should be paired with UST-specific tires for best results.
